the.com/nick

means To steal something small, or to make a small cut or notch — and also British slang for prison, or that precise critical moment ('in the nick of time').

from Origin genuinely murky — 'nick' meaning a notch or groove shows up in the 1500s with no clear parent word. From there it branched everywhere: a 'nick' in time was originally the exact notch marking the right moment; British slang turned a 'nick' into a cell (maybe from the notches jailers cut to tally sentences, though that's folk etymology territory); and 'to nick' something — steal it — likely grew from the same notching sense, as if swiping a little cut off the edge of what wasn't yours. The given name Nick is a separate story entirely, short for Nicholas, from Greek Nikolaos — 'victory of the people.'
